__STATIC_INLINE void MCAN_ClearMessageStoredToRxFifo1 (const MCan_ConfigType *mcanConfig)
 
void MCAN_Init (const MCan_ConfigType *mcanConfig)
 Initializes the MCAN hardware for giving peripheral. Default: Mixed mode TX Buffer + FIFO.
 
void MCAN_InitFdEnable (const MCan_ConfigType *mcanConfig)
 Enables a FUTURE switch to FD mode (tx & rx payloads up to 64 bytes) but transmits WITHOUT bit rate switching INIT must be set - so this should be called between MCAN_Init() and MCAN_Enable()
 
void MCAN_InitFdBitRateSwitchEnable (const MCan_ConfigType *mcanConfig)
 Enables a FUTURE switch to FD mode (tx & rx payloads up to 64 bytes) and transmits WITH bit rate switching INIT must be set - so this should be called between MCAN_Init() and MCAN_Enable()
 
void MCAN_InitTxQueue (const MCan_ConfigType *mcanConfig)
 Initializes MCAN queue for TX INIT must be set - so this should be called between MCAN_Init() and MCAN_Enable()
 
void MCAN_InitLoopback (const MCan_ConfigType *mcanConfig)
 Initializes the MCAN in loop back mode. INIT must be set - so this should be called between MCAN_Init() and MCAN_Enable()
 
void MCAN_Enable (const MCan_ConfigType *mcanConfig)
 Enable MCAN peripheral. INIT must be set - so this should be called between MCAN_Init()
 
void MCAN_RequestIso11898_1 (const MCan_ConfigType *mcanConfig)
 Requests switch to Iso11898-1 (standard / classic) mode (tx & rx payloads up to 8 bytes).
 
void MCAN_RequestFd (const MCan_ConfigType *mcanConfig)
 Requests switch to FD mode (tx & rx payloads up to 64 bytes) but transmits WITHOUT bit rate switching. requested mode should have been enabled at initialization.
 
void MCAN_RequestFdBitRateSwitch (const MCan_ConfigType *mcanConfig)
 Request switch to FD mode (tx & rx payloads up to 64 bytes) and transmits WITH bit rate switching. requested mode should have been enabled at initialization.
 
void MCAN_LoopbackOn (const MCan_ConfigType *mcanConfig)
 Switch on loop back mode. TEST must be set in MCAN_CCCR - e.g. by a prior call to MCAN_InitLoopback()
 
void MCAN_LoopbackOff (const MCan_ConfigType *mcanConfig)
 Switch off loop back mode.
 
void MCAN_IEnableMessageStoredToRxDedBuffer (const MCan_ConfigType *mcanConfig, MCan_IntrLineType line)
 Enable message line and message stored to Dedicated Receive Buffer Interrupt Line.
 
uint8_t * MCAN_ConfigTxDedBuffer (const MCan_ConfigType *mcanConfig, uint8_t buffer, uint32_t id, MCan_IdType idType, MCan_DlcType dlc)

Detailed Description

Purpose

Interface for configuring and using Timer Counter (TC) peripherals.

Usage

  1. Optionally, use TC_FindMckDivisor() to let the program find the best TCCLKS field value automatically.
  2. Configure a Timer Counter in the desired mode using TC_Configure().
  3. Start or stop the timer clock using TC_Start() and TC_Stop().
